Plan a serene escape to turn-of-last-century grandeur between Fifth and Sixth Avenue at the Mansfield Hotel, one of the classic places to stay in New York. This landmark building, dating back to 1903, has been lovingly preserved and outfitted with top contemporary luxuries (that don’t intrude on the romantic, refined feel of the space). The M Bar off the lobby is great for stealing away moments with a paramour, with its private seating areas, domed skylight, mahogany bookshelves, and menu of light bites and specialty cocktails. Meanwhile, the Club Room is a magical Beaux Arts library, complete with a grand fireplace, table games, and a London phone booth room (ideal for carrying out breathy conversations). Upstairs, its 126 handsomely appointed rooms include several suite options and boast elegant Deco furniture, ebony-stained hardwood floors, 300 count linens, pillow-top mattresses, iHome alarm clock radios for the iPod, and flat-panel LCD TVs. Bathrooms are stocked up with Aveda products. If you feel you’ve been luxuriating too long, get motivated and hit the fitness center, complete with a yoga loft.
